Niobium Oxide Capacitors

AVX Niobium Oxide OxiCap® Capacitors are solid electrolytic capacitors based on Niobium Oxide (NbO) anode material instead of traditional Tantalum, offering non-Tantalum material solutions. Niobium is widely available material, next element to Tantalum in the periodic table with many similar features. Several advantages over Tantalum come from Oxides of Niobium that are all stable with very specific performance with each Oxide number, which is utilized in the unique OxiCap® manufacturing technology of processing Niobium Oxide powders as base material for anode.

Niobium Oxide capacitors are extremely stable performance capacitors with high reliability level of 0.5%/1000hrs at 85°C or better, high safety technology with non-burning high resistance failure mode and high break down voltage. AVX OxiCap® is available as low ESR, High CV, low profile, up to 125°C and multi-anode technologies. It is environmentally friendly and RoHS compliant technology in the same form, case size, and same or similar technical performance as standard Tantalum capacitors. Capacitors are offered in voltage rate up to 10Vr and high Capacitance. Majority of series meet AEC-Q200 requirements. All Niobium Oxide capacitors are supplied in orange color encapsulating material.
